Design of the ASTM E119 fire environment in a large compartment

November 1, 2019
Author(s)
Chao Zhang, William L. Grosshandler, Ana Sauca, Lisa Y. Choe
This paper presents a basis for designing the ASTM E119 fire environment in a large compartment of about 10 m wide, 7 m deep and 3.8 m high constructed in the National Fire Research Laboratory of the National Institute of Standards and Technology. Using

Magnetic Ground State and Magnetic Excitations in Black Dioptase Cu 6 Si 6 O 18

November 1, 2019

A. Podlesnyak, O. Prokhnenko, S. E. Nikitin, A. I. Kolesnikov, M. Matsuda, Sachith E. Dissanayake, Timothy R Prisk, H. Nojiri, I. F. Diaz-Ortega, L. M. Anovitz
The low-temperature magnetic properties and magnetic structure of fully dehydrated black dioptase Cu 6Si 6O 18 have been studied by single-crystal neutron diffraction and magnetization measurements in magnetic fields up to 30 T. The intrachain J c and

Measurements and Predictions of Thermophoretic Soot Deposition

November 1, 2019
Author(s)
Amy E. Mensch, Thomas G. Cleary
A thin laminar flow channel with a transverse temperature gradient was used to examine thermophoretic deposition of soot aerosol particles in experiments and modeled in Fire Dynamics Simulator (FDS) simulations. Conditions investigated included three

Nestor: A Tool for Natural Language Annotation of Short Texts

November 1, 2019
Author(s)
Michael Brundage, Rachael Sexton
Nestor is a software tool that annotates natural language CSV (comma-separated variable) files, with a UTF-8 encoding, using a process called tagging [1]. The outputted annotated datasets (as either a CSV or .h5 file) can be used for different analysis

Optical-Fiber Power Meter Comparison between NIST and LAMETRO

November 1, 2019
Author(s)
Johnny Jimenez, Maria Ugalde, John H. Lehman, Igor Vayshenker
We describe the results of a comparison of reference standards between the National Institute of Standards and Technology (NIST-USA) and Laboratorio de Metrologia, Instituto Costarricense de Electricidad (LAMETRO-ICE, COSTA RICA) for optical fiber-based

Recent trends in crystallography a current IUCr journals perspective

November 1, 2019
Author(s)
Andrew J. Allen
The International Union of Crystallography (IUCr) publishes papers in nine scientific journals, including its high-impact, cross-cutting open-access journal, IUCrJ, plus its data publication, IUCrData. Where are these papers cited? To what degree are

Reversible Epitaxial Electrodeposition of Metals in Battery Anodes

November 1, 2019
Author(s)
Jingxu Zheng, Qing Zhao, Tian Tang, Jiefu Yin, Calvin D. Quilty, Genesis D. Renderos, Xiaotun Liu, Yue Deng, Lei Wang, David C. Bock, Cherno Jaye, Esther S. Takeuchi, Kenneth J. Takeuchi, Amy C. Marschilok, Lynden A. Archer
The propensity of metals to form irregular and non-planar electrodeposits at liquid/solid interfaces has emerged as a fundamental barrier to high-energy, rechargeable batteries that utilize metal anodes. We report an epitaxial mechanism to regulate

Selective spin inversion in solution by magic field cross polarization

November 1, 2019
Author(s)
Joel Tolman, Luke Arbogast
A pulsed element is proposed allowing the selective inversion of a single 1H nucleus, without regard to the presence of other degenerate 1H nuclei, provided that it is coupled to a heteronuclear spin with adequate chemical shift resolution in a 2D

Towards Estimating the Uncertainty Associated with 3D Geometry Reconstructed from Medical Image Data

November 1, 2019
Author(s)
Marc Horner, Karim O. Genc, Stephen M. Luke, Todd M. Pietila, Ross T. Cotton, Benjamin Ache, Kevin C. Townsend, Zachary H. Levine
Patient-specific computational modeling is increasingly being used to assist with the visualization, planning and execution of medical treatments. This trend is placing more reliance on medical imaging to provide an accurate representation of anatomical

A Graph-based Automatic Services Composition based on Cost Estimation Heuristic
